Overview
The AI-3629-SF-LW307-R is a magnetic audio indicator manufactured by PUI Audio, Inc. It operates on a DC input with a rated voltage of 48V and a functional range of 9 to 48V. The device produces an acoustic output at a frequency of 2.9kHz, achieving a sound pressure level of 88dB at 48V measured at a distance of 10cm. Power consumption is specified as 15mA. This component is designed for chassis mounting applications.
Feature Summary
- Internally driven magnetic buzzer design requiring no external driver circuitry
- Wide operating voltage range supporting 9V to 48V DC inputs
- Flange mount configuration for secure chassis installation
Applications
- Industrial control panels
- Medical equipment status indication
- Security system alerts
Procurement Notes
Verify the obsolete product status before procurement planning. Confirm that the 48V rated voltage aligns with your system's power supply capabilities. Ensure mechanical compatibility with the designated flange mounting location. Check for available substitute components if lead times are critical due to end-of-life status.
Selection Notes
Select this component when a self-contained, internally driven audible indicator is required. The wide voltage tolerance allows flexibility in power distribution designs. The specific 2.9kHz frequency provides distinct audibility in noisy environments. Verify that the 88dB SPL meets regulatory and safety requirements for the intended application space.
Part Context
This part belongs to the AI series of audio indicators from PUI Audio, Inc., a manufacturer specializing in sound solutions for industrial and medical sectors. The company has over 40 years of experience in producing transducers and buzzers. This specific model represents their magnetic buzzer technology optimized for reliable operation across varying DC voltages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should evaluate current PUI Audio offerings or third-party equivalents with matching voltage, frequency, and mounting specifications.
